Continental 62583 Lower Radiator Coolant Hose

Continental Molded part number 62583 is a lower radiator coolant hose built for vehicles that use a 1.440-inch inside diameter at both ends and a 36.380-inch molded length. It transfers glycol-based coolant through the cooling system with an exact OEM configuration for a direct-fit replacement.

Key Features

• Lower radiator coolant hose for the engine cooling system
• 1.440 in. inside diameter at Hose 1 and End 2
• 36.380 in. molded hose length
• EPDM tube and cover with synthetic reinforcement
• Meets or exceeds SAE 20R4EC Class D1 specifications
• OE-shaped design for accurate routing and fit

Product Details

This Continental Molded hose is engineered for direct replacement service on applications such as the 2006-2009 Chevrolet Impala, lower; 2005-2008 Pontiac Grand Prix, lower; 2006-2007 Chevrolet Monte Carlo, lower; 2008-2009 Buick Allure, lower; and 2008-2009 Buick LaCrosse, lower. The molded profile helps maintain the original hose path, while the EPDM construction and synthetic reinforcement are selected for coolant-system durability. Part number 62583 is also a useful reference when searching for a Continental 62583 radiator coolant hose or a molded lower hose for these GM applications.

This part cross-references Dayco 72365 and Gates 23120 for the same application.

Common Cooling System Issues

• Lower radiator hose leakage from age, heat cycling, or cracking
• Coolant loss caused by hose deterioration at the molded bends
• Restricted coolant flow from a damaged or collapsed hose
• Improper routing when replacing a worn OE-style lower hose
• Cooling-system service on GM vehicles with the specified lower hose layout

Installation Notes and Tips

Verify hose routing, end diameters, and molded shape against the original part before installation. Inspect adjoining clamps, radiator necks, and engine fittings for wear or corrosion, and replace any damaged sealing surfaces during service. Confirm the hose is seated fully and routed without twist so the cooling system maintains proper flow.

Quality Assurance

Continental Molded hoses are built to meet or exceed SAE 20R4EC Class D1 requirements, with an exact OEM configuration intended to match the original application geometry.
